Ocular Pressure Regulation
First Claim
1. A method of placing an ocular device into the eye, comprising:
- providing a fluid drainage tube having a first end and a second end;
forming a self-sealing incision in the cornea into the anterior chamber of the eye;
introducing the fluid drainage tube through the self-sealing incision and into the suprachoroidal space through a cyclodialysis created via a cannula; and
placing the fluid drainage tube such that when implanted into the eye the first end of the drainage tube opens into the suprachoroidal space and the second end of the drainage tube opens into the anterior chamber, so as to provide aqueous pressure regulation.

Abstract
This invention comprises a flexible ocular device for implantation into the eye formed of a biocompatible elastomeric material, foldable to a diameter of 1.5 mm or less, comprising a fluid drainage tube having at one end a foldable plate adapted to locate the device on the inner surface of the sclera in a suprachoroidal space formed by cyclodialysis, said drainage tube opening onto the disc at one end and opening to the anterior chamber when implanted into the eye at its other end, so as to provide aqueous pressure regulation. Also provided are methods for the treatment of glaucoma utilising the flexible ocular device, and an ocular pressure spike shunt.

9. A method of placing an ocular device into the eye, comprising:
-
providing an ocular instrument having a tip;
providing a fluid drainage tube having a distal portion and a proximal portion;
forming an incision in the cornea into the anterior chamber of the eye;
pushing the tip of the ocular instrument into an angle between the iris and the cornea and into a space between the ciliary body and sclera; and
deploying the fluid drainage tube through the space created by the tip of the ocular instrument by advancing the drainage tube such that the distal portion of the drainage tube opens into the suprachoroidal space and the proximal portion of the drainage tube opens into the anterior chamber when implanted into the eye. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of placing an ocular device into the eye, comprising:
-
forming an incision in the cornea to provide an opening into an anterior chamber of the eye;
inserting a fluid drainage tube into the anterior chamber through the opening;
pushing a tip of the ocular instrument into an angle between the iris and the cornea and into a space between the ciliary body and the sclera; and
placing the fluid drainage tube in a position in the eye so that a first end of the tube communicates with the anterior chamber and a second end of the tube communicates with the suprachoroidal space, the tube providing a fluid flow pathway between the anterior chamber and the suprachoroidal space. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A method of placing an ocular device into the eye, comprising:
-
providing a fluid flow member having a fluid flow passageway and a positioning element adapted to locate the fluid flow member on the inner surface of the sclera in the suprachoroidal space;
inserting the fluid flow member into the anterior chamber through a self-sealing incision in the cornea;
guiding the fluid flow member along a pathway that passes through an angle between the iris and the cornea; and
inserting the positioning element of the fluid flow member in the suprachoroidal space such that the fluid flow passageway fluidly couples the anterior chamber and the suprachoroidal space. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)

42. A method of placing an ocular device into the eye, comprising:
-
providing a fluid drainage tube having a foldable anchor member;
forming an incision to provide an opening into the anterior chamber of the eye;
forming an opening into the suprachoroidal space;
inserting a fluid drainage tube with the anchor member in a folded state into the anterior chamber through the incision and into the suprachoroidal space through the opening; and
unfolding the anchor member while the anchor member is in the suprachoroidal space so that the anchor keeps the fluid drainage tube in a position that provides a fluid passageway between the anterior chamber and the suprachoroidal space. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49)

50. A method of placing an ocular device into the eye, comprising:
-
forming a cyclodialysis in the eye;
inserting a fluid drainage tube through the cyclodialysis via a transcorneal approach into the eye; and
implanting the fluid drainage tube in the eye such that a first end of the fluid drainage tube is located within the suprachoroidal space on an inner surface of the sclera, wherein the first end of the drainage tube opens into the suprachoroidal space and a second end of the drainage tube opens into the anterior chamber when implanted into the eye, so as to provide aqueous pressure regulation. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57)
